Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide an anti-vortex device for a storage tank to solve the problem mentioned in the background art that, due to the lack of an anti-vortex device, when the liquid flows rapidly in the pipeline, a large number of eddies and rotations are likely to occur, resulting in the generation of noise and vortices, leading to the inhalation of a large amount of air, and causing the problem that the circulation pump is cavitated due to the swirl.

[0006] To achieve the above purpose, the technical solution adopted in this application is: to provide an anti-vortex device for a storage tank, including:

[0007] A tank body, forming an accommodation cavity, and a liquid outlet is arranged at the bottom of the tank body;

[0008] An anti-vortex mechanism, fixedly connected in the accommodation cavity at the liquid outlet, and the anti-vortex mechanism is used to turbulently flow the target liquid before discharging it from the liquid outlet, so that vortices cannot be formed;

[0009] The anti-vortex mechanism includes a first anti-vortex plate and a second anti-vortex plate. The first anti-vortex plate and the second anti-vortex plate are cross-connected, and the lengths of the first anti-vortex plate and the second anti-vortex plate are greater than the diameter of the liquid outlet.

[0013] Preferably, the first card slot is opened at the middle position directly below the first anti-vortex plate, and the second card slot is opened at the middle position directly above the second anti-vortex plate.

[0014] Preferably, both the first anti-vortex plate and the second anti-vortex plate have a first anti-vortex portion and a second anti-vortex portion;

[0015] There are two second anti-vortex portions, and the two second anti-vortex portions are located on both sides of the first anti-vortex portion, used to separate the first anti-vortex portion from the liquid outlet to ensure that the device has sufficient feeding and discharging flow rates.

[0016] Preferably, the length of the first anti-vortex portion is 3 times the diameter of the liquid outlet, so that the downward fluid has sufficient resistance and space when flowing in the reverse direction.

[0017] Preferably, the tank body is wrapped with a rock wool insulation layer to reduce energy loss and ensure the normal operating temperature of the tank body.

[0018] Preferably, a spray ball is provided at the top of the tank body. The spray ball sprays cleaning liquid onto the inner wall of the storage tank to clean the inner wall of the storage tank and prevent the growth of microorganisms and pollutants.

[0022] The beneficial effects of an anti-vortex device for a storage tank provided by this application are as follows: The anti-vortex mechanism is installed at the liquid outlet at the bottom inside the tank. The anti-vortex mechanism can change the flow direction of the fluid, making the fluid flow along a more straight path, thereby reducing the generation of eddies. In addition, the anti-vortex mechanism can also disperse the energy of the fluid, evenly distribute the energy into the pipeline cross-section, and reduce energy concentration. Therefore, the anti-vortex mechanism can improve the working efficiency of the circulation pump, avoid the influence of cavitation on the circulation pump caused by swirl, and at the same time can reduce the liquid level on the liquid surface inside the storage tank, thereby increasing the water storage capacity.

[0034] Please refer to Figures 1 to 4 , and now a vortex prevention device for a storage tank provided by an embodiment of the present application will be described.

[0035] Specifically, a vortex prevention device for a storage tank includes a tank body 1, which forms a receiving cavity 2. A liquid outlet 3 is provided at the bottom of the tank body 1. The liquid outlet 3 is connected to a circulation pump in the system, and the liquid outlet 3 is communicated with the receiving cavity 2. Three support legs 5 are provided at the bottom of the tank body 1 for supporting the tank body 1. Two equipment lifting lugs 9 are symmetrically provided at the top of the tank body 1. The tank body 1 includes an inner tank 101 and an outer tank 102. A heat insulation layer is provided between the inner tank 101 and the outer tank 102. As a preferred embodiment, the heat insulation layer is a rock wool heat insulation layer 6, which is used to reduce energy loss and ensure the normal operating temperature of the tank body 1. A spray ball 7 is provided at the top of the tank body 1. The spray ball 7 extends into the receiving cavity 2. The spray ball 7 sprays cleaning liquid onto the inner wall of the storage tank to clean the inner wall of the storage tank and prevent the growth of microorganisms and pollutants. A sanitary pressure manhole is also provided on the tank body 1, and the sanitary pressure manhole is hermetically connected through a sealing cover 8. In order to ensure the safety of the equipment and the system, a rupture disc 10 is installed at the top of the tank body 1 in the receiving cavity 2.

[0036] An anti-vortex mechanism 4 is installed at the liquid outlet 3 within the accommodation chamber 2. The anti-vortex mechanism 4 is used to turbulently flow the target liquid before it is discharged from the liquid outlet 3, preventing the formation of a vortex. This avoids the vibration and cavitation caused by the vortex from damaging the equipment and the circulation pump, enabling the device to operate continuously.

[0037] Specifically, the anti-vortex mechanism 4 includes a first anti-vortex plate 401 and a second anti-vortex plate 402. The first anti-vortex plate 401 and the second anti-vortex plate 402 are cross-connected, and the lengths of the first anti-vortex plate 401 and the second anti-vortex plate 402 are greater than the diameter of the liquid outlet 3.

[0038] As a preferred embodiment, the first anti-vortex plate 401 is provided with a first card slot 4011, and the first anti-vortex plate 401 has a first clamping portion 4012; the second anti-vortex plate 402 is provided with a second card slot 4021, and the second anti-vortex plate 402 has a second clamping portion 4023; the first card slot 4011 is clamped to the second clamping portion 4023, and the second card slot 4021 is clamped to the first clamping portion 4012.

[0039] To improve the stability and force balance of the first anti-vortex plate 401 and the second anti-vortex plate 402, the first card slot 4011 is opened at the middle position directly below the first anti-vortex plate 401, and the second card slot 4021 is opened at the middle position directly above the second anti-vortex plate 402.

[0040] Preferably, both the first anti-vortex plate 401 and the second anti-vortex plate 402 have a first anti-vortex portion and a second anti-vortex portion; there are two second anti-vortex portions, and the two second anti-vortex portions are located on both sides of the first anti-vortex portion, used to separate the first anti-vortex portion from the liquid outlet 3 to ensure that the device has sufficient feeding and discharging flow rates, and the end of the second anti-vortex portion away from the first anti-vortex portion is fixedly connected to the inner tank 101. The length of the first anti-vortex portion is 3 times the diameter of the liquid outlet 3, so that the downward fluid has sufficient resistance and space when flowing in the reverse direction.

[0041] During operation, the liquid in the accommodation chamber 2 is first turbulently flowed by the first anti-vortex plate 401 and the second anti-vortex plate 402 before being discharged from the liquid outlet, preventing the formation of a vortex. This avoids the vibration and cavitation caused by the vortex from damaging the circulation pump, enabling the device to operate continuously.

[0042] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
